Maureen joins a select band of authors who set their books in the 'perceived to be' unfashionable/unsaleable-market setting of Birmingham.
As far as I know the only other crime authors to set a series in Birmingham are:
Valerie Kershaw who wrote a five book series featuring a radio presenter (published between 1993 and 2000)
Judith Cutler who wrote two series set in Birmingham, published between 1998 and 2003, one with an amateur sleuth and another with a policewoman. (She is probably the best well known of the local crime writers, based on my library experience).
Plimmer and Long - an ex-cop and ex-con who co-wrote a two book series between 2000 and 2001.
Chris Collett who began a series in 2004 featuring policeman Tom Mariner which stands at eight books so far. (Tom Mariner has many female fans in my reading group!)
If anyone knows of any more series set in Birmingham (looking at you Martin E :-)) then do please pop them in the comments.

If you are after the Black Country, then Thomas JR Dean has a series set there in the 1950s: Once Upon a Time in The Black Country. Alex Grecian's second book in his Scotland Yard Murder Squad series is called The Black Country and is set in a fictional Midlands mining town. Patrick Thompson's Execution Plan and Seeing the Wires are set in Dudley.
There are also some further suggestions in the comments.
